Paper 2: Principles of the Food Processing and Preservation Module 15: Food Concentration as Preservation: Different Methods of Concentration 15.1INTRODUCTION Food preservation is the process in which, food is not only processed but also its desirable attributes (sensorial andnutritional) are sustained up to the maximum possible time duration. Principle of food preservation constitutes removal of water and subsequent reduction in water activity. There are three broad categories of food preservation methods (figure 1)i.e. inhibitionof microorganisms andchemicaldegradation;inactivation of ...

Food Preservation: Food Safety & Hygiene Level 2 Food preservation can be achieved through: Low temperatures High temperatures Dehydration Chemical methods (e.g. salt, sugar, vinegar) Physical methods (e.g. vacuum packing, smoking) Preservation Methods Chilling Refrigeration is a common method of preserving food. Generally, the colder the temperature, the slower bacteria will multiply. Fridges should be between 1°C and 4°C, although some micro-organisms (particularly spoilage organisms) can grow at these temperatures. Freezing Freezing preserves food by ...
